Summary

Force cast a &Vec<T> to &[T]

Details

In function Table::as_ref, a reference of vector is force cast to slice. There are multiple problems here:

To guarantee the size is correct, we have to first do Vec::shrink_to_fit. The function requires a mutable reference, so we have to force cast from immutable to mutable, which is UB.
Even if (1) is sound, &Vec<T> and &[T] still might not have the same layout. Treating them equally may lead to UB.
